Hints
Hold the device with both hands and support them against the wall if possible.
To complete a measurement, the DIST button may be held pressed until the measurement is
done and the Laser switches off. This helps making measurements without shaking the
device.
Take care with metal objects! Each kind of
ferromagnetic metal near the device leads to wrong
measurements. This no longer only holds for the
helmet, but also for other objects carried at the body
like SRT gear (steal karabiners), carbide container,
belts, or tools, which all can get to near to the device.
For precise measurements it is recommended to
mark the rear ‘exit point’ of the Laser beam
(picture). Place this point as near as possible to the
survey point.
Switching the display illumination off completely saves a lot of power.
For best performance, the device should be calibrated in regular intervals.
Error Codes
If an error occurs during a measurement the text “Info” appears on the screen together with
one of the following error codes:
252: Temperature too high
253: Temperature too low
255: Received signal too weak
256: Received signal too high
257: Too much background light
260: Laser beam interrupted
If the “2nd” symbol is shown at the top of the display, one of the two acceleration sensors
does not work correctly. The device still works with only one sensor but precision is
compromised and the calibration is no longer valid if it was made with both sensors.
